Helmet testing system

Abstract

The invention discloses a helmet testing system, belonging to the technical field of helmet evaluation. The helmet testing system comprises a head model, a liquid module, a gas module, a detection module and a controller, wherein a liquid input pipeline in the liquid module is installed in the middle part of the head model and inputs liquid into the head model; a gas pipeline in the gas module is mounted beside the liquid input pipeline and inputs gas into the head model to change the size of the head model; a helmet is fixed on the head model; the detection module is mounted on the head model and the helmet and connected with the controller; and the system is connected with a power source. According to the invention, the structure of the head model is changed and the size of the head model is adjusted by inputting liquid and gas, so demands of people in China are met; the helmet testing system overcomes the problems that head models in conventional helmet production have only one shape and cannot meet demands of people and has the advantage that the head model is adjustable; and the size of the head model is adjusted according to actual needs, and then whether prepared helmets fit designated head models are tested.

Description

technical field [0001] The invention belongs to the technical field of helmet evaluation, and in particular relates to a helmet testing system. Background technique [0002] Modern helmets are used to prevent projectiles or fragments from penetrating the head, prevent the head from directly colliding with hard and high-energy objects, effectively protect the human head, eyes, and face, and do not affect the human body's vision and activities. It is used in military , medical, sports, entertainment and other industries have a wide range of applications. In order to ensure the rationality of the ergonomics of the entire helmet, countries around the world have carried out in-depth research on 3D head shape acquisition, modeling and standardization. Jeffrey M.T. of the U.S. Air Force Operations Center used the KGR30 mass analyzer produced by Cosmic Electronics to test and study the center of gravity of the "head model-flying helmet" system, but the research did not directly mea...

Problems solved by technology

[0003] According to the deficiencies in the prior art above, the technical problem to be solved by the present invention is to propose a helmet testing system. By changing the structure of the head model, inputting liquid and gas, changing the size of the head model, and adapting to the needs of Chinese people, the helmet is solved. The shape of the head model in production is single and not suitable for the needs of Chinese people. It has the advantage of adjustable head model. Adjust the size of the head model according to actual needs, and then test whether the helmet is suitable for the specified head model.
